Understanding Coffee Nutrition
Black coffee is essentially calorie-free. At 1.0 kcal per 100 g serving, it provides negligible protein, carbohydrate and fat — none of the three macros are present in any meaningful amount.
For athletes and anyone tracking macros, coffee's own calories are trivial enough to ignore in a meal log. Its real relevance to training and recovery comes from caffeine, not macros — this cup carries 40mg. What usually adds meaningful calories to a cup of coffee is milk, cream or sugar, none of which are reflected in black coffee's numbers here.
